Answer:
a. 64, 128, 256 (geometric)
b. 11, 13, 15 (arithmetic)
c. 53, 61, 69 (arithmetic)
Step-by-step explanation:
(a) Each term is twice the previous term. so it is geometric with a common ratio of 2
(b) The difference between each term is 2. So it is arithmetic with a common difference of 2
(c) The difference between each term is 8. So it is arithmetic with a common difference of 8

Answer:
Chord 12 cm long subtends an angle of 40 degrees at the center of a circle.
θ= 40° = 0.698 rad
Let R be the radius of circle.
Chord Length = 2Rsin(θ/2)
12=2R sin (0.698 /2)
R= 17.54
Ans: Radius of circle = 17.54 cm
The answer is true;
because if a triangle had more than one obtuse angle it would become like a rhombus or something else so it is not possible to remain a triangle and have more than one obtuse angle c:
